The GPU's average benchmark score of 54247 places it at the 86th percentile among all GPUs.

The combined picture shows a system where both components perform at high levels, but the CPU holds a slight edge over the GPU in percentile terms (92 vs. 86). The combined 89th percentile ranking reflects a balanced but CPU-leaning configuration. The CPU's nearest rival, the Core i9-13900KF, is essentially identical in performance (0.1% difference), while the GPU's closest competitor, the RTX 4080 SUPER, is also within 0.1%. This suggests that both components are near the top of their respective performance tiers.

GPU Analysis

The NVIDIA GeForce RTX 4080 is built on the Ada Lovelace architecture using TSMC's 5 nm process, with a die size of 379 mm² and 45,900 million transistors. The GPU operates at a base clock of 2205 MHz and boosts to 2505 MHz, with memory running at 1400 MHz (22.4 Gbps effective). The card features 16 GB of GDDR6X memory on a 256-bit bus, delivering 716.8 GB/s of memory bandwidth.

The RTX 4080 includes 9728 shading units, 304 texture mapping units, and 112 raster operation processors. For ray tracing and AI workloads, the card has 76 RT cores and 304 tensor cores. The pixel rate is 280.6 GPixel/s, and the texture rate reaches 761.5 GTexel/s. The GPU delivers 48.74 TFLOPS for both FP32 and FP16 operations (1:1 ratio).

In benchmark terms, the RTX 4080's PassMark G3D score of 34457 and DirectX 12 score of 132 indicate strong DirectX performance. The DirectX 11 score of 314 and DirectX 10 score of 204 show scaling across API generations. For compute-heavy rendering workloads, the GPU compute score of 20671 and Geekbench OpenCL score of 214739 demonstrate substantial parallel processing capability. The Vulkan score of 263779 is particularly strong, suggesting excellent performance in Vulkan-based renderers and games.

The 76 RT cores provide dedicated hardware for ray-traced rendering, while the 304 tensor cores accelerate AI-driven features like DLSS and neural network inference. With 16 GB of VRAM and 716.8 GB/s bandwidth, the card can handle large texture sets and complex scenes at high resolutions without memory bottlenecks. The triple-slot design and 320 W TDP indicate substantial cooling requirements, with the suggested 700 W PSU providing adequate headroom for the entire system.

Balance and Bottleneck

The performance data reveals a system where the CPU slightly outpaces the GPU in relative terms. The CPU's 92nd percentile ranking versus the GPU's 86th percentile suggests that in CPU-bound workloads, the RTX 4080 may not be fully utilized, while in GPU-bound scenarios, the processor has sufficient headroom to feed the graphics card.

The CPU's 3DMark 16-thread score of 11201 and max-threads score of 15509 indicate strong multi-threading capability that can keep up with the GPU's rendering demands. The PassMark multithread score of 58589 and data compression score of 793645 show the CPU excels at heavily threaded tasks that might otherwise bottleneck a high-end GPU.

However, the GPU's PassMark DirectX 12 score of 132, while respectable, is lower than its DirectX 11 score of 314, suggesting the card may be more optimized for older API workloads. This could create a bottleneck in newer DirectX 12 titles where the GPU's architecture is pushed harder. The GPU's G2D score of 1239 is notably lower than its G3D score of 34457, indicating the card is heavily optimized for 3D rendering rather than 2D desktop tasks.

In gaming scenarios, the CPU's single-thread performance (3DMark single-thread score of 1187, Cinebench R23 single-core of 2238.5) is sufficient to avoid bottlenecking the GPU at high frame rates. The PassMark single-thread score of 4608 reinforces this. The balanced nature of this pairing means that neither component is likely to be the consistent limiting factor; instead, the bottleneck shifts depending on the specific workload's threading characteristics and API usage.

Who Should Build It

This desktop configuration targets users who require maximum multi-threaded CPU performance alongside high-end GPU acceleration. The Core i9-13900K's 24 cores and 32 threads, combined with the RTX 4080's 9728 shading units, make this system suitable for professionals in 3D rendering, video production, and scientific computing.

Gamers seeking high-refresh-rate experiences at 1440p or 4K resolutions will find the CPU's single-thread performance (3DMark single-thread score of 1187) and the GPU's 86th percentile ranking adequate for demanding titles. Content creators working with 4K or 8K video will benefit from the CPU's Cinebench R23 multicore score of 38271.5 and the GPU's compute capabilities (Geekbench OpenCL score of 214739).

Software developers compiling large codebases will appreciate the PassMark integer math score of 207792 and the data encryption score of 46609. Students in engineering or computer science fields can leverage the CPU's 32 threads for parallel computing assignments while using the GPU's tensor cores for machine learning projects. Small business workstations requiring ECC memory support (available on the CPU) and reliable multi-threaded performance for database or virtualization workloads would also benefit from this configuration.

Gaming Performance

No measured FPS data exists for this exact CPU-GPU combination in the FACT PACK, so all gaming performance figures below are estimates derived from the benchmark scores. The CPU's 92nd percentile ranking and the GPU's 86th percentile ranking suggest strong gaming capability, but exact frame rates cannot be confirmed.

Based on the 3DMark Steel Nomad DX12 score of 6567, the RTX 4080 should handle DirectX 12 titles with high settings at 1440p and 4K resolutions. The GPU's PassMark DirectX 11 score of 314 suggests even better performance in older DirectX 11 games, potentially enabling very high frame rates at 1080p and 1440p. The Vulkan score of 263779 indicates strong Vulkan API performance, which is relevant for modern game engines.

The CPU's 3DMark 8-thread score of 8520 and 16-thread score of 11201 provide ample processing power for game logic, physics, and AI. The PassMark physics score of 3140 supports this. For competitive shooters at 1080p with high refresh rates, the CPU's single-thread performance (PassMark single-thread score of 4608) should prevent bottlenecks, allowing the GPU to deliver maximum frame rates.

At 4K resolution, the GPU becomes the primary factor, and the RTX 4080's 16 GB VRAM and 716.8 GB/s bandwidth should accommodate high-resolution textures. The 76 RT cores enable ray-traced effects, though the performance impact will vary by game. Overall, the estimated gaming performance places this system in the high-end tier, capable of running most titles at high or ultra settings across common resolutions.

Upgrade Path and Platform

The Core i9-13900K uses the Intel Socket 1700 platform, which supports both DDR4 and DDR5 memory through a dual-channel memory bus. The CPU provides PCIe Gen 5 with 16 lanes, while the RTX 4080 uses PCIe 4.0 x16, leaving PCIe 5.0 bandwidth available for future GPU upgrades. The platform supports ECC memory, which is unusual for consumer processors and valuable for workstation use.

The system requires a 700 W power supply according to the GPU's suggested PSU rating, with the CPU's 125 W TDP adding to the total power draw. The RTX 4080 uses a 1x 16-pin power connector and occupies a triple-slot form factor, so case compatibility and cooling must be considered. The GPU measures 310 mm in length, 140 mm in height, and 61 mm in width.

For future upgrades, the CPU's unlocked multiplier allows overclocking to extend its lifespan. The PCIe 5.0 support from the CPU means that next-generation GPUs using PCIe 5.0 interfaces will be compatible, though the RTX 4080's PCIe 4.0 interface will not bottleneck current games. The dual-channel memory support allows for memory capacity and bandwidth upgrades, though DDR5 is already supported alongside DDR4.

A sensible next upgrade would be replacing the RTX 4080 with a newer GPU when the GeForce 50 series becomes available, as the predecessor-successor relationship indicates the RTX 4080 is now end-of-life. The CPU's 92nd percentile ranking suggests it has remaining lifespan, and the platform's PCIe Gen 5 support ensures compatibility with future high-bandwidth devices.
